Synthesis and characteristics of a new three-dimensional molybdoantimonate Na4Sb12Mo5O35

“…Owing to the flexible interpolyhedral linkages and the variety of different coordination geometries about Sb III, V and Mo VI , molybdoantimonates such as K 5 H 2 SbMo 6 O 24 Á (H 2 O) 7 [5] and MSbMo 2 O 8 (M ¼ K, Li, Cu) [6][7][8] show good structural complexity and diversity. Since the lone pair of electrons of Sb(III) often lead to very distorted polyhedra, we undertook a synthetic and structural study on the antimony molybdates.…”
